ORE oR COAL WASHER.

SPECIFICATION forming part of Letters Patent No. 624,499, dated May 9, 1899.

' Application filed September 6,1898. Serial No. 690,255. (No model.)

' To all whom it may concern.-

Be it known that I, ALBERT I. JONES, a citizen of the United States, and a resident of Hancock, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Ore or Goal Tashers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has forits main object to provide a simple, economical, and efficient coal and ore washing apparatus in which a plurality ofplungers are run independent of each other from the same shaft to have variablespeed reciprocation,although they may work in unison.

The invention also contemplates a singleplunger apparatus of the character named; and it consists in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

- Figure 1 of the drawings represents a partlysectional view of a portion of an ore or coal Washing apparatus embodying my improvements, said view being longitudinally of said apparatus; Fig. 2, an elevation of the apparatus, partly in transverse section; Fig. 3, a plan view, partly in horizontal section, illustrating a detail of said apparatus; Fig. 4, an elevation of a portion of said detail; and Figs. 5 to 8, inclusive, are illustrations of constituents pertaining to the aforesaid detail.

Referring byletter to the drawings, A designates each of a pair of tanks cast integral with each other and a separating-partition B, the walls of these tanks being for the most part convergent toward bases having strengthening-ribs rising therefrom, a pair of these ribs being shown in Fig. 2. Each tank is provided at its lower end with a discharge-opening and contains a partition 0, parallel to the one aforesaid, the upper ends of the tankwalls being vertical. The partition 0 in each of the twin tanks divides the latter into two compartments at its upper end, shoulders of this partition and an opposite tank-wall constituting seats for a screen D, the latter being held to place on said seats by means of stay-strips E, bolted to said partition and tank-wall, as clearly illustrated in Fig. 1.

Made fast to the partition 0 of each tank, below the screen-seat shoulder of the-same, is

an inclined baffle-plate F, and the tank-compartment between the partitions B O is occupied by a plunger G, provided with vertical rods II, that extend up through sleeves atthe ends ofa horizontal bar 1, nuts or other means being employed in connection with said rods to clamp the plunger tight against the lower ends of said sleeves. The rods II also extend up through guides constituting parts of bridge-bars J, made fast tostandards K, that are bolted to the tanks, these standards being provided with bearings for a shaft L, with tion with the bars I, have eccentric connection.

With the exception of certain details'conpitmen M, the general construction and arrangement of parts thus far described are similar to what is common in the prior state of the art. Therefore the novel features of my improvements are hereinafter set forth.

One of the bearings for shaft L is provided with a laterally-extended flanged boss N, having an eccentric bore in whichsaid shaft has rotation, this detail being best illustrated in Fig. 8. Loose on boss N are a pair of beltpulleys P Q, the latter pulley being provided with a pin R, havinga circular head loose in an angular block S, that slides in a groove of a crank-plate T, the latter being made fast on shaft L against the outer or driving pulley Q aforesaid.

The connection between shaft L and head of each pitman M is herein shown as comprisring U, having a hub keyed on said shaft, another eccentric ring V, fitting said hub, a bolt W in the latter eccentric ring, having a conical head fitting the annular groove of the former eccentric ring, and a clamp-nut X, run on the screw-threaded outer end of the bolt. In order that the head of thebolt W may be engaged with the groove of eccentric ring U, the latter is provided with a transverse aperture of sufficient diameter intercepting said groove, this aperture being shown in Figs. 1, 3, and 7.

Each pitman-head is in two sections bolted together around the eccentric ring V'between a flange of the same and the other eccentric ring U, the length of throw of the pitman bewhich'plunger-pitmen M, in pivotal count-30 cerning driving mechanism, as well as the; eccentric connection of shaft L and plungering an annularly-dovetail-grooved eccentric.

'ing regulated by adjustment of one eccentric ring on the hub of the other.

In practice as the pulleyQ revolves on the stationary boss N the pin R, moving with said pulley at a constant distance from its center, aetuates the crank-plate T to thereby impart variable-speed revolution to shaft L, whereby the independent plungers are accelerated on their descent, but retarded on their ascent. Incidental to rapid descent of eachindependent plunger water in the corresponding tank is forced up through material on the screen within said tank, producing an agitation that causes sand and other light impurities to separate from said material and overflow with the water, a supply of the latter being kept runas it is possible to devise other means for the same purpose, and although it is preferable to have all the plungers Work in unison the organization of the apparatus may be such as to provide for alternate descent of said 'plungers even though they follow one another for a time on the ascent.

Having thus describedmy invention, What I claim as new, and desire to secure by Letters Patent, is

1. In an ore or coal washing apparatus of the character described, a plunger having a pitman in eccentric connection with a shaft, a boss extending laterally from one of the shaft-bearings and provided with an eccentric bore in which said shaft has rotation, a pulley loose on the boss, a crank fast to the aforesaid shaft, and a pulley projection having play longitudinally of the crank.

2. In an ore or coal washing apparatus of the character described, a plunger in connection with a pitman, an eccentric ring engagin g the head of the pitman, another eccentric ring having a hub loosely engaged by the one aforesaid, means for holding the first of these eccentric rings in adjusted position with respect to the other, a shaft in rigid connection with said hub, a boss extending laterally from a shaft-bearing and provided with an eccentric bore in which said shaft has rotation,'a pulley loose on the boss, a crank fast to the aforesaid shaft, and a pulley projection having play longitudinally of the crank.

3. In an ore or coal washing apparatus of the character described, a plurality of independent plungers having pitmen in eccentric connection with a shaft, a boss extending laterally from one of the shaft-bearings and provided with an eccentric bore in which said shaft has rotation, a pulley loose on the boss, a crank fast to the aforesaid shaft, and a pulley projection having play longitudinally of the crank.

4:. In an ore and coal Washing apparatus of the character described, a plurality of independent plungers in connection with pitmen, an eccentric ring engaging the head of each pitman, another eccentric ring having a hub loosely engaged by the one aforesaid, means for holding the first of these eccentric rings in adjusted position with respect to the other, a shaft in rigid connection with said hub, a

boss extending laterally from a shaft-bearing and provided with an eccentric bore in which said shaft has rotation, a pulley loose on the boss, a crank fast to the aforesaid shaft, and a pulley projection having play longitudinally of the crank.

5. In an ore or coal washing apparatus of the character described, a drive-shaft, an cecentric having rigid hub connection with the shaft and provided with an inside annular dovetail groove intercepted by a transverse aperture, a bolt having a conical head received in said groove through said aperture, another eccentric ring. engaged by the bolt and hub of the former eccentric ring, a clampnut run on the screw-threaded end of the bolt, a pitman having its head in fit upon the hubfitting eccentric ring,and a plunger connected to the opposite end of the pitman.

In testimony that I claim the foregoing I have hereunto set my hand, at Hancock, in the county of Houghton and State of Michigan, in the presence of two witnesses.

ALBERT I. JONES.
